       2 . Profile arrangement according to  claim 1 , characterized in that the support part portion has at least one rib ( 80 ) and the holding portion ( 78 ) of the switching strip profile ( 76 ) is integrally joined to a narrow side of rib ( 80 ). 
   
   
       3 . Profile arrangement according to  claim 2 , characterized in that support part ( 72 ) has several ribs ( 80 ), which project with their end portion freely from a base portion of support part ( 72 ), the holding portion ( 78 ) of switching strip profile ( 76 ) resting on the end portions of ribs ( 80 ) and is integrally joined thereto. 
   
   
       4 . Profile arrangement according to  claim 1 , characterized in that the holding portion ( 38 ;  42 ;  46 ) of switching strip profile ( 36 ;  40 ;  44 ) is provided with projections, slots, ribs and/or steps. 
   
   
       5 . Profile arrangement according to  claim 1 , characterized in that the holding portion ( 42 ) of switching strip profile ( 40 ) is provided with at least one undercut and is positively joined to the support part in the vicinity of the undercut. 
   
   
       6 . Profile arrangement according to  claim 1 , characterized in that the support part ( 66 ;  72 ) is constructed as an elongated strip and provided with fixing means ( 68 ) for fixing to a vehicle body ( 52 ). 
   
   
       7 . Profile arrangement according to  claim 1 , characterized in that the switching strip profile ( 76 ) is curved along its longitudinal direction and/or along its transverse direction. 
   
   
       8 . Profile arrangement according to  claim 1 , characterized in that the holding part of the switching strip profile is at least sectorwise made from electrically conductive material. 
   
   
       9 . Profile arrangement according to  claim 1 , characterized in that the support part is made at least sectorwise from electrically conductive material. 
   
   
       10 . Profile arrangement according to  claim 1 , characterized in that the switching strip profile ( 36 ) has at least two mutually spaced conductors ( 31 ;  33 ) running parallel to the longitudinal direction of the switching strip profile ( 36 ), a first conductor ( 31 ) being constructed as a capacitor electrode for generating an electrical field and a second conductor ( 33 ) as a shield electrode for influencing the electrical field. 
   
   
       11 . Profile arrangement according to  claim 10 , characterized in that the conductors ( 31 ,  37 ) of the switching strip profile ( 36 ) come into electrical contact on deforming the switching strip profile. 
   
   
       12 . Profile arrangement according to  claim 10 , characterized in that at least one third conductor ( 35 ) is provided within the switching strip profile ( 36 ) on a side of the first conductor ( 31 ) and spaced therefrom which substantially faces the second conductor ( 33 ). 
   
   
       13 . Method for the manufacture of a profile arrangement with a support part in the form of a plastic moulding and an at least sectorwise, elastically flexible switching strip profile, characterized by the following steps:
 inserting the switching strip profile in a plastic injection mould, so that a holding portion of the switching strip profile is at least sectorwise accessible from a cavity of the plastic mould,   moulding the support part, the plastic used for moulding the support part at least sectorwise contacting in the flowable state the holding portion of the switching strip profile and   removing the support part with the moulded on switching strip profile.   
   
   
       14 . Method according to  claim 13 , further characterized by the insertion of the switching strip profile in a matching slot of a plastic injection mould and applying a vacuum to the slot for sucking on the switching strip profile.
